Mastering Spring Cloud

By: Piotr Mińkowski

Overview of this book

Developing, deploying, and operating cloud applications should be as easy as local applications. This should be the governing principle behind any cloud platform, library, or tool. Spring Cloud–an open-source library–makes it easy to develop JVM applications for the cloud. In this book, you will be introduced to Spring Cloud and will master its features from the application developer's point of view. This book begins by introducing you to microservices for Spring and the available feature set in Spring Cloud. You will learn to configure the Spring Cloud server and run the Eureka server to enable service registration and discovery. Then you will learn about techniques related to load balancing and circuit breaking and utilize all features of the Feign client. The book now delves into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures. Before running an application on Docker container s, you will master testing and securing techniques with Spring Cloud.

Repository backend types

All of the previous examples in this chapter have used the filesystem backend, which means that the config files were loaded from the local filesystem or classpath. This type of backend is very good for tutorial purposes or for testing. If you would like to use Spring Cloud Config in production, it is worth considering the other options. The first of them is a repository backend based on Git, which is also enabled by default. It is not the only one version control system (VCS) that can be used as a repository for configuration sources. The other option is SVN, or we can even decide to create a composite environment, which may consist of both Git and SVN repositories. The next supported backend type is based on a tool provided by HashiCorp, Vault. It is especially useful when managing security properties such as passwords or certificates. Let's take a closer look at each of the solutions listed here.
